How do I get Netscape 6.2 to use some other mail client when I click on a email link on a web page?

I'm testing out a web application on Netscape 6.2 and every time I click on an email link, Netscape tries to send mail using its own email client rather than Eudora. How do I fix this so that it'll use Eudora instead?
